Besvic Power Meter Energy Monitor Plug, 13A Electricity Usage Power Consumption Monitor Socket with 7 Monitoring Modes, Overload Warning, Amp Wattage Volt Meter Analyzer (2Pack)

I had an old plug-in energy monitor which I have never been able to use properly, The instructions were difficult to read and I could never get it to work. It has inputs for different rates at different times on different days and other menu options I could not fathom, so I bought two of these and another of a different make to see if one was easier to use than the other. The other was a Decdeal energy Monitor and was slightly more expensive than one of these which are branded besvic. I found both monitor types easy to use. you just have to press the COST button for four seconds and it starts flashing for you to input your electricity cost in £ per kWh. I didn't bother with any other inputs, because I just wanted to measure electricity consumption for 24 hours for several different devices. After 24 hours, all three meters gave a cost in £ so I was able to identify which appliances used most electricity and which used very little. I found the appliances on standby and mobile phone chargers used very little, whilst my high-end gaming PC with three monitors costs about £0.50 per day and the tropical fish tank about the same. One of my fridge freezers used £0.48 per day but the other used only £0.22 per day (it is newer). Negative feedback comments around Electricity Monitors mostly centre around an unreadable display and inaccurate measurements. I have to say that a bright, illuminated display would be worth having, but I never had any trouble reading the display on these monitors, although you have to be within two feet and looking fairly square on. In terms of accuracy, when measuring same device, over three days, I found that both besvic meters recorded £0.50 and the Decdeal showed £0.48, so there was not as much variation as I had feared. This does not prove they are giving an absolute accurate figure, but at least they were consistent. In terms of power measurement, the meters showed about 100W of power consumption for my PC on it's own, and 250W consumption with the three monitors turned on as well. That is equivalent to two and a half 100W light bulbs which seems about right to me, so I think they are reasonably accurate. Overall I found these easy to set up and use. With the recent astronomical increase in the price of electricity I think these are worth buying to help reduce energy costs by becoming more aware of the high cost appliances in your household.

A good product, great for checking electricity running costs for my many gadgets. On the negative side, every time I am using it for a different appliance the cost per kilowatt hour has to be reprogrammed, it would be more convenient to be able to clear the data but keep the cost constant. However this is a minor irritation and on the whole I am pleased with the items

I have ThermPro temp/humidity measurer and these 2 match precisely the temprature read, so I know they are accurate.Very easy to set up. it has START temp - i.e. if the temprature is THIS or BELOW it will activate... and STOP so if the temprature is THIS or ABOVE, it will stop.You can also reverse START/STOP to make it cool the room, it AUTOMATICALLY SWAPS into COOLING mode, so you don't need to do anything, other than set desired tempratures.Super good and Accurate.ps if you are using your hands to set it up and touching the MEASURER, you need to give it couple of seconds (like 30 or so) for it to settle and the metal to cool down, then you get accurate reading. Cause I was super angry, when I saw that it doesn't measure correctly, but then I realised it was ME TOUCHING THE METAL, so you need to wait till it cools down and stabilises. ITS SUPER ACCURATE, I can vouch for it.

It works well as a power meter.

I bought this product as i have just purchased a few solar panels and batteries and an inverter and i wanted to work out what i could sensibly power from them. To start with i plugged my laptop through this plug and was pleasantly surprised at the low power. I then plugged it into my inverter ( a modified sine wave 2kw device) i plugged in a lava lamp to see what the power rating was, after about 10 mins i could smell burning. I unplugged the device and could detect that it was warm to the touch, the pictures tell what i found inside.I was cross that this thing i had bought might have caused a fire. Returned it for a refund. Besvic contacted me and were interested in finding out what the problem was. In the meantime i had purchased a replacement slightly more expensive meter that had also failed after a few hours with a familiar smell !I received a free replacement which i will use on 240 mains only.In conclusion the supplier went out of their way to try and resolve this issue. DONT USE WITH A MSW INVERTER !
